l VIIVIIIRO'VEMIINT IN HARROWS.

The Schedule referred to in these Letters Patent and making part of the same.

To 'whom it may concern Be it known that I, HENRY C. mzo'rr, of Osage,

4in the county of Mitchell, and State ofdlowa, haveiudesigned to provide more useful, ecient, and convenient borrows than' now in use.

' The inventionA consists in the comhinationof the hai-row witha truck, under an arrangement whereby yit may be readily elevated above tbeground for transportation, by the operator, whether` sitting'- on the truck, or walkingr behind it. l

Figure 1 represents a side elevation with the axle, cut through at the line a: x.

Figure 2 represents afront view taken; on ythe line 'yy.

Figure 3 represents a plan view of the harrow, when detached, from the truck.

Similai letters of reference indicate corresponding parts.

I arrange the flaming of the harrow in' the rectangular forni, represented in iig. 3, and composed of the Ytwo triangular parts A B, hinged together at the bases thereof, each part being provided with similar transverse bars C, for supporting additional teeth.

The vertex of each triangle at B is Aconnected b'y a I chain to a yoke, E, above the truck, and supported centrally ou a rod, F, jointed lto the framing by staples at the centre G.

The said rod and the chains rise up through vopenings in the axle of the truck.

The front and rear points of the harrow are connectedby chains H, respectively, to bell-crank' levers I and K, and the free arms of these levers are counected together by the connecting-rod L.

The free end of the lever I is arranged at the side of the seat, for convenient access when riding thereon, and the other is placed at the rear of the machine, to be readily reached when walkngbehind, and for greater convenience a handle, M, may be attached thereto.

N represents the draught-chain, by whichthe power is applied from the tongue.

By this arlangement for suspending the barrow, it is caused' to work very steadily, and may be instantly raised ofI" the ground, and suspended in a level condition, as will be readily perceived.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is.-

The yoke E, supported and connected to the barrow I
